It's (going to be) the name of `pip`'s -experimental feature that may improve the speed of dependency resolution -of the new resolver. By avoid downloading whole wheels to just -obtain metadata, it is especially helpful when `pip` has to do -heavy backtracking to resolve conflicts. - -Thanks to {{pip 8532#discussion_r453990728 "Chris Hunt's review on GH-8537"}}, -my mentor Pradyun Gedam and I worked out a less hacky approach to inteject -the call to lazy wheel during the resolution process. A new PR {{pip 8588}} -was filed to implement it—I could have *just* worked on top of the old PR -and rebased, but my `git` skill is far from gud enuff to confidently do it. - -Testing this one has been a lot of fun though. At first, integration tests -were added as a rerun of the tests for the new resolver, with an additional flag -to use feature `fast-deps`. It indeed made me feel guilty towards [Travis][], -who has to work around 30 minutes more every run. Per Chris Hunt's suggestion, -in the new PR, I instead write a few functional tests for the area relating -the most to the feature, namely `pip`'s subcommands `wheel`, -`download` and `install`. - -It was also suggested that a mock server with HTTP range requests support -might be better (in term of performance and reliablilty) than for testing. -However, {{pip 8584#issuecomment-659227702 "I have yet to be able to make -Werkzeug do it"}}. - -Why did I say I'm half way there? With the parallel utilities merged and a way -to quickly get the list of distribution to be downloaded being really close, -what left is *only* to figure out a way to properly download them in parallel. -With no distribution to be added during the download progress, the model of this -will fit very well with the architecture in [my original proposal][]. -A batch downloader can be implemented to track the progress of each download -and thus report them cleanly as e.g. progress bar or percentage.
